Quick explanation
(Physics only) (HT only) State that iron is used in the core because it is easily magnetised
- This point belongs to Induced potential, transformers and the National Grid (physics only) (HT only), especially Transformers (HT only).
- You need to be able to (Physics only) (HT only) State that iron is used in the core because it is easily magnetised.
- The key ideas to know are physics only and HT only.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

Why it matters
This objective helps connect Transformers (HT only) to exam-style questions, flashcards, and revision notes for Induced potential, transformers and the National Grid (physics only) (HT only).
Quick student answer
What should you know about (Physics only) (HT only) State that iron is used in the core because it is easily magnetised?
Direct answer
In Physics, this page helps you answer questions about (Physics only) (HT only) State that iron is used in the core because it is easily magnetised within Induced potential, transformers and the National Grid (physics only) (HT only). Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are Transformers (HT only) direction cue 169 and Transformers (HT only) cause cue 170.
Key terms
- Transformers (HT only) direction cue 169: A bench-top compass mapping prediction cue for (Physics only) (HT only) State that iron is used in the core because it is easily magnetised.. It helps identify the relevant magnetic field, current, transformer coil, motor effect or generator induction evidence, while keeping Transformers (HT only) distinct from neighbouring GCSE Physics ideas.

- Transformers (HT only) cause cue 170: A scrapyard lifting magnet prediction cue for (Physics only) (HT only) State that iron is used in the core because it is easily magnetised.. It helps identify the relevant magnetic field, current, transformer coil, motor effect or generator induction evidence, while keeping Transformers (HT only) distinct from neighbouring GCSE Physics ideas.

Common trap
National Grid transformer reasoning: avoid magnetic field...: Instead, identify the exact Unit 4.7 idea in Transformers (HT only), then explain how it links to a current-carrying wire between magnetic poles and the objective to state that iron is used in the core because it is easily magnetised.
